Comparison of Subgingival Mechanotherapy With and Without the Use of a Perioscope: Clinical Trial

Non-surgical treatment is the basic form of disease treatment periodontitis. Its first stage is the mechanical removal of dental plaque along with the control of risk factors. Subgingival mechanotherapy, also known as scaling and root planing (SRP) is the next stage, aimed at the subgingival area. Perioscopy makes possible direct real-time visualization of the root surface during the procedure. The research results published so far indicate improvement or no significant differences clinical parameters after SRP procedure using a perioscope vs traditional subgingival instrumentation. The aim of this study is to indicate, or not, clinical, biochemical (level of pro-inflammatory cytokines) and microbiological (A. actinomycetemcomitans, P. gingivalis, T. denticola) differences after periodontitis treatment using the traditional method vs. using a perioscope.
